Interface FactSurface

WHERE A FACT IS PRESENTED TO AN OPERATOR — the presents column (2026-08-06-channel-contract.md revision 6, ruled 2026-09-17).

servedAs made declaration → address readable and killed the sourceStereo blind spot, where "served under another name" and "never built" were the same silence. This is the same move for declaration → surface: without it a fact with no tooltip reads exactly like a fact whose tooltip nobody joined, and the 2026-09-17 census could only measure the gap by substring — its own words, "a COVERAGE SKETCH, not a finding".

help is a LIST because the data refuses a singular: gate is presented by six entries and headAmp by two. The cardinality that HOLDS, and is ratcheted, runs the other way — a help id is claimed by at most one fact.

A fact no surface presents declares presents: null, never an absent key: an adjudicated "nothing teaches this" is a decision a ratchet can count, and an omission cannot be told apart from a fact somebody skipped.

i18n (revision 7): the catalog key(s) a real widget binds with t() to label this fact's OWN control — never a name correlation, never a substring. A fact with no such call has no entry, whether or not the top-level presents itself is null (soloSafe carries i18n with no help; that is the same "a decision, never an omission" the column already keeps, one layer down).

OWED, its own lane and its own amendment first: surface (the chips and panels that render it, in the vocabulary manual-coverage-conformance derives from the web-ui's registries).
